Comma separated vectors - R

> Months = c(1:24)


> paste(as.character(Months), collapse=", ")
[1] "1, 2, 3, 4, 5....24"

> paste(as.character(one), sep="' '", collapse=", ")
[1] "1, 2, 3, 4, 5....24"

What about if you want to go with quotes around the numbers then the “shQuote” function comes in handy and i’ve just learnt that.

Double quotes:

> cat(paste(shQuote(Months, type="cmd"), collapse=", "))

Single quotes:

> paste(shQuote(one), collapse=", ")

In addition, to output a csv file, which would be write.csv or write.table.

> write.table(matrix(as.character(Months),nrow=1), sep=",",
             row.names=FALSE, col.names=FALSE)

"1","2","3","4","5", …..,”24”

> write.csv(matrix(as.character(Months),nrow=1),row.names=FALSE)

"V1","V2","V3","V4","V5", ….”24”
"1","2","3","4","5", …...”24”
